A man accused of stabbing more than a dozen people at a Houston-area college told investigators that he had fantasized about cannibalism and necrophilia and about cutting off people’s faces and wearing them as masks, according to a court document made public on Thursday.

The suspected gunman in the Lone Star College’s North Harris campus shooting was arrested in Plano by the Gulf Coast Violent Offenders Task Force. Friday’s arrest marks the second in the Lone Star College shooting incident.

Authorities continue their search for the gun used in Tuesday’s shooting at Lone Star College. Reports indicate that officials believe that the alleged gunman,22-year-old Carlton Berry, had assistance in getting rid of the weapon.

This week’s gunfire at a Houston-area college prompted new calls Wednesday for allowing concealed handgun license holders to carry their weapons into Texas college buildings and classrooms as a measure of self-defense.
